The molecular weight should be at least 2000 but not so high that the compound is insoluble in water or weakly alkaline solutions.  The acid groups may be introduced by esterification.  Specified naturally occurring materials include heparin (which contains acid sulphuric acid ester groups) and compounds such as agar, carageen, alginic acid, dextran and hyaluronic acid which contain esterifiable carbohydrate or carbohydrate-like residues in the molecule.  An exhaustive list of synthetic substances which may be sulphated or phosporylated is given.  Specifications 700,761 [Group IV(b)], 753,319 and 757,800 [both in Group IV(a)] are referred to.

Abstract: 185,866. Pollak, J. E., (Naamlooze Vennootschap Hengelosche Electrische en Mechanische Apparatenfabriek). June 17, 1921. Protective a r r a n g ements.-The main switch of an electrical installation is provided with a single protecting arrangement without additional leads to the motors or other apparatus, in order to prevent closure of the switch unless the resistanoe of the installation exceeds a certain value. In the arrangement shown, the main switch 8 is locked in the off position by means controlled by a coil 4 connected across the lines 5, 6 in parallel with the apparatus to be protected. In order to release the lock, the coil 4 is connected to the supply conductors 10, 11 through a push-button or like switch 9 or through pre-contact pieces on the main switch, but unless the resistance of the installation exceeds a certain value the coil 4 does not receive sufficient current to release the lock. In the case of a motor installation, each motor of the installation must be switched off before the main switch can be closed.

Title: Improvements in sound records and the production thereof
IPC: G11B3/70
Filed: 1942-12-01
Abstract: 561,809. Sound record discs. COOKE, F. G., and HAMMANS INDUSTRIES, Ltd. Dec. 1, 1942, No. 17073. [Class 40 (ii)] [Also in Group VIII] Relates to sound record discs of board bonded with synthetic resin, synthetic resin varnish, or like material and comprising a spongy or collapsable layer or layers at the surface or surfaces of the disc where the sound record is to be formed, said layer or layers being impregnated with the bonding material and pressed. According to the invention, the pressing is adapted to produce an annular depression between a central projection a<2> and a rim a<1>, and causes sufficient exudation of the bonding material to form a surface c suitable for the reception of the sound track. This avoids the separate operation of coating the annular depression with a surface layer as described in Specification 561,708.

Each blade root has a recess 24 for a collar 26 engaging axial thrust bearing 28, a nut 48 being provided for preloading the bearing. The butt end of the blade has a shift ring 34 connected by a pin and shift yoke to a tube 46 on which the piston 68 is mounted and to which a latch rod 86 is fixed. The rod 86 has a shoulder 88 for co-operation with a spring- loaded latch pin 90 to provide a high pitch stop. The pin moves out at a predetermined propeller speed but upon engine failure the resilient means in housing 62 will thrust the propeller blades to feathered position before the pin moves inwardly. In the case where said resilient means is air pressure a low pitch stop is also provided, the latch rod abutting a stop at the end of the casing. The supply of pressure oil to the left end of cylinder 58 is under governor control.
